SAFETY-RAZOR.

Specification of Letters Patent. Patent edMay 27, 1919. 7

Application filed June 26. 1918. Serial No. 241,915.

I guished from the operation of those safety razors which have a handle fixed in angular relation to the blade and impose the difliculty of keeping the blade at the proper angle while shaying. I In furtherance of this general ob ect, I

have provided a safety razor characterized by a tu'bular'handle shaped at one end to form a holder and guard pickets for a double edge blade, and a clamping member movable longitudinally within the handle for clamp ing the blade to the holder.

Other objects and attendant advantages will be appreciated as the invention becomes better understood by reference to the following description when considered in connection with the accompanying drawings, in which Figure 1 is a face view of a safety razor illustrating one embodiment of my improvements;

Fig. 2, a side view thereof;

Fig. 3, a longitudinal sectional view through the razor taken substantially on theline 33 of Fig. 1;

of razor shown in Fig. 7.

Fig. 7, a side view of a modified form 0 my invention; Fig. 8, an end view of Fig. 7; and v Fig. 9,. a perspective view of one of the blades, of which two are used in the form Referring to Figs. 1 to 6 of the drawings, it will benoted'that the handle and blade v holder or backing are integrally formed,

preferably from a piece of tubing cut away at one side to provide the requisite guard pickets for the blade. In both embodiments of my improvements,'the tubular piece 10 constitutes the handle, and one end thereof is cut away on one side, as shown, providing a holder or backing 11 having longitudinal sides shaped to provide guard pickets 12. This holder, substantially semi-circular in cross section, is adapted to receive on its inner side a blade designated by character 13, specially designed for fitting within the curved holder. The blade, also semi-circular in cross-section, has opposed sharpened edges 14 cooperating with the guard pickets 12 and is adapted to be clamped to the holder or backing 11 by a member which will be presently described. To hold the blade in position against sidewise and lengthwise displacement the blade is provided at each end with a notch or recess 15, which receives the fixed lugs or stops 16 when the blade is properly positioned on the holder.

The clamping member or rod, designated generally by reference character 17, for securing the blade to the holder, is permanently associated with the handle and ad-.

justed into and out of clamping position, preferably by a thumb nut 18 threaded onto the end of the rod which projects through the lower end' of the handle. The clamping rod extends longitudinally through the handle 10 and is equipped at-the inner side of the holder with aball clamping head 19 adapted to engage the inner side of the blade about medially between the ends thereof and to be drawn tight against the blade for clamping the same to the holder. This clamping action is effected by drawing the rod lengthwise- .into engagement with an inclined surface 21 on the handle. This inclined surface, in the present instance, is in the form of a tapered opening in a wall 22 at the base of the blade holder,-the hole being'eccentric with respect'to the handle and disposed closer to the blade holder 11. The clamping rod is provided with an annular tapered face 23 cooperating with the tapered surface 21 so that when the thumb nut 18 is tightened against the end 24, the ball end 19 of the rod will be drawn by the action of the inclined surfaces 21 and 23 the handle and an abutment 2 6, constantly urges the rod lengthwise in a direction to withdraw the surface 21, sothat when the thumb nut 18 is unscrewed the clamping head- 19 will be automatically withdrawn from the blade, permitting the same to be easily removed from the holder. means is provided for limiting lengthwise movement of the clamping rod, and in the present instance, consists of a set screw 27 in the end 24 of the handle engaged in a slot in the rod.

In use it will be readily seen that by reason of the peculiar arrangement of the blade with respect to the handle, the razor may be conveniently held to position the blade at any desired angle and by simply rolling the handle between the fingers this angle may be instantly varied. Because of the arrangement of the blade in the longitudinal plane of the handle, the razor may be manipulated with the handle close to the face and at an angle corresponding with the desired angle of the blade as distinguished from the inconvenient manner in which a safety razor must be operated when the handle is positioned at right angles to the blade. The blade may be quickly and easily removed from the holder and clamped again in position as will be obvious, since the blade-clamping means is operated solely by a thumb nut 18.

In Figs. 7 8 and 9, I have illustrated another form of my improvements, differing chiefly in the blade construction. In this form two fiat blades are employed, each having a single cutting edge instead of a single curved blade having double cutting edges. The flat blades 33, each having a single cutting edge 34, are adapted to be clamped by the ball head 19 of a clamping member 17 against a backing 11 suitably shaped to hold the blades in suitable angular relation as shown in Fig. 8. In order to prevent displacement of the blades and to secure them in proper relation on the backing 11, each blade is provided with an opening 35, preferably countersunk, in which the ball end 19 is adapted to engage. It will be manifest when the clamping member is tightened in the manner described with reference to the first embodiment, a pair of flat blades 33 will be rigidly clamped and held in fixed position on the blade holder, that upon loosening the nut 18 the blades may be removed for cleaning and sharpen mg.

It is believed that the foregoing conveys a clear understanding of my improvements, and it should be understood that various changes might be made in the construction and arrangement without departing from the spirit and scope of the invention as expressed in the appended claims.

I claim:

1. A safety razor comprising a handle having a blade holder, a blade, a clamping member movable longitudinally within the handle and overlapping the. blade holder and adapted to clamp an interposed blade to the holder, a spring for constantly urging Suitable the clamping member in a direction to retract the same, and manually operable means for forcing the clamping member in the opposite direction for clamping the blade to the holder and for positively holding the blade in such clamping position.

2. In a safety razor, a handle having formed integrally therewith a blade holder V-shape in cross section, a flat blade adapted to be positioned on each inner flat side of said blade holder with the cutting edge of the blade adjacent to the outer edge of the holder and the back edge of the blade near the bend of the holder, a member disposed between the inclined sides of the V-shaped holder and adapted to clamp both blades thereto, and means for moving said member to clamp the blades.

3.
